While there are many colors to choose from, you have to be very selective when printing your marketing material. If you are not careful it is easy to select the wrong colors, or overdo it with too many.

The first thing you should do is consider the primary colors and whether or not any of them will work for you. If nothing else, this will give you a good jumping off point. The three pigment colors that are considered primary include: blue, red, and yellow.

It is important to note that two primary colors combined leads to a secondary color. So while primary colors are a good start, they are far from your only options.

Before you print any marketing material, such as folders or business cards, make sure you consider the color scheme. Are you going to rely solely on primary colors? Or do you have something else in mind?
